Tesla is far from the only big company unhappy with the decision. Companies the likes of Google, Apple, Microsoft, Facebook, Adobe and others took out a full page ad in The New York Times, The Wall Street Journal, and New York Post asking the president to maintain the agreement.

Musk’s departure from Trump’s advisory council follows that of Uber CEO Travis Kalanick earlier this year following Trump’s immigration order. When Musk explained why he chose to remain on the council he cited wanting to advise the president with a goal to “accelerate the world’s transition to sustainable energy.” With Trump pulling out of the landmark climate agreement, it seems Musk had decided his energy is best devoted elsewhere.
